How to Choose the Right Sized Solar System for Your Home
When you are looking to install solar panels on your roof, there is a good chance that you want to do away with your energy bills. Mostly, homeowners will consider their average electricity consumption when deciding the size of a solar system. However, the energy that solar systems produce depends on the number of panels in the systems and the amount of sunlight that reaches the panels. Here are a few factors to help you choose the right solar system size.
Consider Your Average Electricity Use
Electricity consumption in the United States varies by both state and household. As such, you can only determine the ideal solar system size by looking at a recent copy of your own electricity bill. Solar installers will have a look at the bill and factor in the number of peak sun hours your location gets to determine the size and the number of solar panels you need. They will also need to increase the system size to account for the power lost when the panels convert from DC to AC.
Solar Efficiency And Weather Conditions
Solar panels differ significantly, with expensive premium panels being more efficient and working effectively under cloudy conditions. While premium panels are associated with a high initial cost, homeowners will recover their investment over time. The high power that these panels generate makes them a worthwhile investment for those who live in areas with poor weather conditions.
Other factors that affect the efficiency of solar systems include local weather, shading and panel placement. As much as the solar installer will assess the site and strive to achieve maximum efficiency, cloudy weather, annual snowfall and roof angle could compromise performance. This can be overcome by the use of larger solar systems.
Generally, customers in areas with snowfall or many cloudy days will need to install large solar systems. The local installer will also consider tree cover and dust to ensure that the performance of your system is not hurt.
Look At Your Roof Space And Angle
Roof space and angle will also affect the solar system size. Panels have to be tilted at a certain angle so as to optimize their exposure to the sun. Solar installers should have the necessary expertise and technology to ensure that solar power generation is optimized.
In the event that the solar installer finds that the roof space is inadequate during their site visit, homeowners can choose to install smaller solar systems that only cover part of their energy. Homeowners can also opt for ground-mounted systems if the size of their property allows. This will enable them to meet their energy needs without the limitations associated with the available roof space.
Avoid the “Rebound Effect”
The “Rebound Effect” refers to the tendency by homeowners to increase their energy consumption after installing solar panels. This can be attributed to the notion that the panels generate “free” electricity. If energy use increases, you will still owe your utility if the installation of the solar system was based on your electricity consumption.
If energy use increases, homeowners can either expand their solar systems in future or control usage through energy-efficient appliances and conscious energy-conserving lifestyle.
If you are convinced that your property has the potential to generate solar power, you should consult an expert solar power installer and get them to visit your property.
